Hello,
I am trying to write a matrix 'A' to a text file. I would like the data written to file like this:
A =
2 0 2 1 2 0
2 2 2 1 0 0
1 2 2 0 0 2
The code given below does not contain the 'A = '. How can I also include the 'A = ' to be written to the file also? Thanks for your help and time.
Here is the code that I have so far:
%%Generation of Random 3 x 6 Matrix
A = randi([0,2],3,6);
dlmwrite('myFile.txt',A,'delimiter','\t')

What should be the tabs on the 'A =' line and the visually empty line after that?

Can it be saved like:
A =
\newline
matrix
I am not sure how to answer your question. I would like the constant and matrix be saved bascially the way it is displayed in Matlab:
Thanks for your help and time!

output = evalc(A);
fid = fopen('myFile.txt', 'wt');
fwrite(fid, output);
fclose(fid);
